Manager StartupUI; in Novell SUSE Linux Enterprise Server, they

can do so by selecting Start>System>More Programs>Dell SAS

RAID Storage Manager.

When the login window appears after launching Dell SAS RSM,

administrators enter their username and password and select

either Full Access mode (which enables both viewing and chang-

ing configurations) or View Access mode (which enables only

viewing and monitoring configurations)  from the drop-down

menu. If the computer is networked, administrators should enter

the login information for the computer itself, not the network.

Using Full Access mode requires the root administrator username

and password.

After login, Dell SAS RSM automatically detects and displays

the system’s storage controllers, physical drives, and virtual disks.

The application’s main window includes three panels: a left panel

showing the system devices, a right panel showing additional details

about a particular device, and a bottom panel showing system

event log entries.

The left panel presents either a physical or logical view of the

system and devices, depending on the selected tab. The Physical

tab shows the hierarchy of physical devices; storage controllers are

enumerated with the disk drives and other devices attached to the

ports. The Logical tab shows the hierarchy of controllers, virtual

disks, and disk groups.

The right panel includes three tabs, with different tabs displayed

depending on the type of device selected in the left panel and the

login mode:

Properties: This tab displays information about the selected 

device. For example, if a controller is selected, this tab shows

information such as the controller name, nonvolatile RAM 

(NVRAM) size, and number of device ports.

Operations: This tab lists the operations that can be per-

formed on the selected device. Dell SAS RSM only displays

this tab in Full Access mode.

Graphical View: This tab displays a color-coded view of the

selected device’s storage capacity (see Figure 1). Dell SAS RSM

only displays this tab for physical drives and virtual disks.

The bottom panel displays the system event log entries, includ-

ing the ID number, an error level indicating event severity, the date

and time, and a brief description.

The Dell SAS RSM Configuration Wizard enables administrators

to create new virtual disk configurations on the PERC 5/i and the

SAS 5/iR without rebooting the systems. It includes three modes

for the PERC 5/i:

Auto Configuration: Of the three modes, this one provides the

quickest and simplest way to create a new storage configura-

tion. Using the available physical disks, the wizard creates the

optimal virtual disk with minimal administrator intervention.

Guided Configuration: This mode creates a new storage con-

figuration based on a series of queries. The wizard uses the 

information provided by the administrator to create an opti-

mal storage configuration using the available physical disks.

Manual Configuration: This mode is the most flexible of 

the three, but is designed for advanced users with in-depth 

knowledge of storage configurations.

Saving and adding virtual disk configurations

In addition to creating new configurations, administrators can import 

existing configurations to help prevent virtual disks from being lost 

when migrating physical disks or to help simplify configuration of 

a new controller. They can use Dell SAS RSM to save an existing

configuration to disk by performing the following steps:

 1.  

Select a controller in the left panel of the application’s main 

window, then select Operations>Advanced Operations>

Configuration>Save Configuration in the menu bar.

 2.  

In the Save dialog box, enter a name for the configuration 

file, then click the Save button.

Administrators can import a saved configuration as follows:

 1. 

 Select a controller in the left panel of the application’s main 

window, then select Operations>Advanced Operations>

Configuration>Add Saved Configuration in the menu bar.

 2.  

A message box displays a warning that unstable conditions

may arise from differences in physical devices in two configu-

rations. Click the Yes button.
